Patricia Bay Current Meter Deployed 2012-08-12

The Nortek Vector MicroSquid 4868 was deployed on 2012-08-12 at Patricia Bay. Patricia Bay is located in the Saanich Inlet, on the southern tip of Vancouver Island. This device is a Current Meter. Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current metres have a sensor head that contains 3 acoustic transducers, a tilt sensor, a temperature sensor and a pressure sensor. The instrument transmits a short pulse of sound, and then listens to its echo to measure the change in pitch or frequency. The change in pitch can determine the velocity of the current. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

诺泰克（Nortek）Vector MicroSquid 4868型设备于2012年8月12日在帕特里夏湾（Patricia Bay）布放。帕特里夏湾坐落于温哥华岛南端的萨尼奇湾（Saanich Inlet）内。该设备为海流计（Current Meter）。声学海流计（Acoustic Current Meters, ACM）借助多普勒效应测量海流的流速与流向。Aquadopp型海流计的传感器探头集成3个声学换能器、1个倾斜传感器、1个温度传感器及1个压力传感器。该仪器发射一段短声波脉冲，随后监听回波以获取频率变化，通过该频率偏移量可推算海流流速。本次布放采用固定式平台。本次布放获取的数据已完成存档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外共享，所有数据均遵循既定规范完成质量管控，并产出配套衍生数据产品。
